Thomson SPB 16 ADJ Super Pillow Block 1" Bore Linear Bearing Housing 1.5" OD

Thomson SPB 16 ADJ Super Pillow Block 1" Bore Linear Bearing Housing 1.5" OD

The Thomson SPB 16 ADJ is a Super Pillow Block linear bearing housing designed to support 1-inch round linear shafts in motion control and linear slide applications. The housing is machined from aluminum and accepts a self-contained linear ball bearing insert. The "ADJ" designation indicates an adjustable (clamp-style) design that allows the bearing preload to be set by tightening the top clamp bolt, accommodating wear and enabling precise radial clearance adjustment without replacing the bearing unit.

Applications

Thomson Super Pillow Blocks are widely used in industrial linear motion systems wherever a 1-inch linear shaft needs a rigid, mountable bearing support. Common applications include machine tool slides, automation and pick-and-place equipment, conveyor and material handling systems, X-Y positioning tables, and general factory automation machinery. The adjustable clamp design makes the SPB series particularly suited to environments where bearing preload needs to be tuned or re-adjusted in the field. Thomson Industries has been a leading manufacturer of linear motion components since the 1940s, and the SPB series pillow blocks are standard hardware in a wide range of OEM and replacement linear motion builds.
